Cartridge holder system
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention generally relates to cartridge holding systems and more specifically, to cartridge holding systems that permit the user to quickly catalog, store, and retrieve videocassettes. 
     2. Description of the Prior Art 
     The concept of cartridge holders is well known in the art. Typically, the cartridge holders contain shelves for holding the cartridge in a position where viewers can read the label on the cassette or the cartridge holder. One of the problems with storage of videocassettes is that numerous programs are often stored on the same videocassette tape and at different locations on the tape. To find a particular program, one runs the tape forward until the desired program appears or by locating the program on the videocassette tape through the locating index displayed on the videocassette recorder (VCR). The present invention provides a storage system and indexing system that permits the user to quickly identify the location of a particular program and to quickly retrieve the videocassette from the usually crowded cabinet located under the television set.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to FIG. 1, reference number 10 identifies the circular rotatable information disk for storing information on the title of a recorded program, the location of the recorded program on the videotape, and the videocassette cartridge where the program is located. Information disk 10 has a circular central opening 14 for mounting on a turntable similar to the manner records are mounted on a turntable. The top surface of information disk 10 includes three discrete annular regions for entering information on the recorded videocassette program. Each of the annular regions is divided into radial segments for entering information on one recorded program. The inner annular region 13 shows the tape location, the middle annular region 12 contains a short descriptive title of the recorded program and the outer annular region 11 identifies the videocassette cartridge that the program is located on. For example, the listing &#34;1893 Louie Ander. 20&#34; indicates that the recorded program on Louie Anderson is located on videocassette cartridge number 20 and at the location marker 1893. Knowing the information on the location of the particular program permits the user to quickly find the selected program on a videocassette tape that may contain many different programs. 
     In order to read and store the information disks we provide a viewer. FIGS. 2 and 3 show viewer 20 for storing and viewing the information contained on the information disks. Viewer 20 comprises a top transparent panel 21 that permits information disks mounted on turntable 25 and centering pin 26 to be seen by a person looking down at viewer 20. To operate the viewer the user lifts up hinged transparent panel 30 which is hinged to top surface 21 by hinge 31. The user then places the information disk through opening 29 and on turntable 25. The user can then rotate turntable 25 through a thumbwheel 22 that connects to turntable 25 through a shaft and pulley 27, a drive belt 23 and drive pulley 24. By rotating the information disk while peering through a magnifier 33, the operator can quickly scan through the entire list of stored programs to find the selected program. After finding the program the user can remove and store the information disk in the lower portion of the viewer cabinet storage area that contains three stepped compartments 40, 41, and 43. Each of the compartments holds a single information disk with a portion of each information disk visible from above the viewer. By color coding the disks or placing other information identification on the disk, the user can quickly select the proper disk. For example, information disk 53 could be for sporting activities, information disk 51 for movies and information disk 50 for children&#39;s programs. Thus, each of the categories of videocassette programs can be entered on a single disk to facilitate general subject locating of a program. While we have shown turntable 25 driven by a thumbwheel 22, if desired an electric motor drive can be connected to drive pulley 24 to provide continuous or intermittent rotation of turntable 25. 
     One of the difficulties is that the storage space in a television cabinet is usually not very high but is relatively deep. This type of arrangement makes it difficult to store videocassette cartridges in a position where the user can easily view the identification label on the cartridge. In order to overcome this difficulty, we provide a storage rack that permits both horizontal and vertical storage of the videocassette cartridges. 
     FIG. 4 shows a storage rack 60 having a rear storage shelf 58 mounted to a platform 61 through sides 62 and 63 connected by a top board 64. The rear storage shelf is permanently mounted to platform 61 and holds videocassette cartridges in a vertical orientation at the back of a storage cabinet. 
     Located at the front of the storage rack 60 is a front videocassette compartment 59 that is both slidable and rotatable to permit holding videocassette cartridges in a horizontal or vertical orientation. Compartment 59 comprises a back panel 72, a transparent front panel 71, transparent sides 73 and 74, and a bottom panel 75. The panels coact to form an open container that snugly or confiningly holds a videocassette cartridge in the compartment. The transparent panels also permit the user to read information located on any portion of the front edge of a videocassette. 
     Referring to FIG. 5, Fig. 6, and FIG. 7 the various positions of the front compartment are illustrated by side views. FIG. 5 shows a side view with a videocassette cartridge 100 located on the rear storage shelf 58 and a videocassette cartridge 101 located in a vertical position in front compartment 59. FIG. 6 shows the front compartment 59 partially rotated from the vertical position and with the compartment slid forward. That is, a hinge 79 which is shown in greater detail in FIG. 9 permits the user to pivot front compartment 59 with its contents to a position where the compartment 59 holds the videocassette cartridges in a horizontal position. FIG. 7 illustrates front compartment 59 in the horizontal storage position with the videocassette cartridge 101 therein located in a horizontal position. The purpose of having a front compartment 59 that is movable and pivotable is to permit the user to obtain access to the videocassette cartridges located on the rear storage shelf 58 while allowing the information on the videocassette cartridges on both the front compartment and the back shelf to be displayed in a manner that a user can readily see the identification indicia. A reference to FIG. 8 shows a plurality of videocassette cartridges located on the rear storage shelf 58 and in the front compartment 59 with the identification information located on the top portion of each videocassette located within the videocassette cartridge. The information is visible on both rows of videocassette cartridges. The difficulty in storing videocassette cartridges in such a manner is that the dimensions of the television cabinets prevent the videocassette cartridges located in the back row from being removed without removing the videocassette cartridges in front of the rear videocassette cartridges. To remove a videocassette cartridge from the rear row with the present invention the user merely tips the entire front compartment 59 to the horizontal position. With the videocassette cartridges in the horizontal position, as shown in FIG. 7, the user can quickly and easily remove the videocassette cartridge from the rear shelf 58. 
     Referring to FIG. 9, one of the hinges 79 for tipping compartment 59 is shown in greater detail. Hinge 79 connects to back panel 72 of compartment 59 through a member 69a that has a cylindrical pivot rod 91a extending from one side and a cylindrical pivot rod 90a extending from the opposite side. The pivot rod 90a slides in a U-shaped opening located in strip 77 and the pivot rod 90a slides in a similar U-shaped opening located in strip 78. The mounting of the strips on platform 61 permits the user to slide the pivot rods forward or rearward and the circular cylindrical shape of the pivot rods permits the user to rotate the front compartment from a horizontal to a vertical position or vice versa. An identical hinge is located on the other end of compartment 59 and mounts in an identical manner in U-shaped strips 80 and 81 (FIG. 4). 
     Referring to FIG. 10, an assist device is shown attached to back panel 72 of compartment 59. Assist device comprises a member 91 attached to back panel 72 with member 91 having a pivotal connection to one end of leg member 90. The other end of leg member 90 includes a roller 94 that rolls along platform 61. A tension spring 92 has one end that connects to post 93 on member 90 and a second end that connects to eye 95 on back panel 72. 
     In tilting the compartment which is loaded with video cassettes it is sometimes desirable to provide a gentle lowering of the compartment to avoid damaging the video caseettes or spilling the cassettes from the compartment. In operation of the present invention with the assist device, the user grasps compartment 59 and tilts the compartment backward about pivot rod 91. As the compartment 59 is tipped back member 90 is forced rearward. As member 90 is forced rearward as shown in FIG. 11, it causes the tension spring 92 to elongate and provide a counterbalance force to the tipping action. The tension of spring 92 is such that it will not prevent one from tilting the front compartment to the horizontal but will provide a compensating force so that a portion of the weight of the video cassettes is supported by the assist device. While the assist device provides a portion of the support for tilting compartment 59 to the horizontal position, it also provides a portion of the force necessary to tilt the compartment from the horizontal to the vertical position.
